PRE-COLLISION SYSTEM Laser Sensor Inspection

DTC Code DTC Name
Laser Sensor Inspection

DESCRIPTION

The pre-collision city sensor determines the distance between this vehicle and a preceding vehicle using the laser sensor.

CAUTION / NOTICE / HINT

Note:

  • When replacing the pre-collision city sensor, replace it with a new one and be sure to initialize the settings. If a pre-collision city sensor which was installed to another vehicle is used, the information stored in the pre-collision city sensor will not match the information from the vehicle and, as a result, a DTC may be stored.

  • If the pre-collision city sensor has been replaced, or the windshield glass has been replaced or removed/installed, be sure to perform Pre-collision City Sensor Optical Axis Learning.

    Tip:

    Pre-collision City Sensor Optical Axis Learning can be performed by using either One Time Recognition or Sequential Recognition.

PROCEDURE

  1. READ VALUE USING GTS

    1. B415864C01

      *a

      This Vehicle

      *b

      Preceding Vehicle

      *c

      1.67 m (5.48 ft.)

      *d

      1.33 m (4.36 ft.)

      Position this vehicle and another vehicle as shown in the illustration, and then measure the distance between this vehicle and the preceding vehicle.

      Note:

      Perform the measurement indoors in an area where sunlight will not shine directly on the pre-collision city sensor.

      Tip:

      • The distance between the pre-collision city sensor (laser sensor) and the rear bumper of the preceding vehicle should be 3 m (9.84 ft.).

      • The distance between the pre-collision city sensor (laser sensor) and the front bumper of this vehicle is 1.33 m (4.36 ft.).

      • The distance between the pre-collision city sensor (laser sensor) and the preceding vehicle is displayed in the Data List.

      • Do not use a modified car as a preceding vehicle.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the GTS on.

    5. Enter the following menus: Chassis / PCS/LDA/RSA/LVN / Data List.

    6. Read the Data List according to the display on the GTS.

      Lidar Detect Target Distance

      Displays distance of the highest priority object which is detected by Lidar.

      0 to 51.0 m

      Distance between the vehicle and a preceding vehicle

      • When no preceding vehicle is detected, "0 m" (0 ft.) is displayed

      • Displays the distance between the pre-collision city sensor (laser sensor) and a preceding vehicle.

      Tip:

      If "0 m" (0 ft.) is displayed, the pre-collision city sensor (laser sensor) is malfunctioning.
